Indifference curves and budget lines
The Principle of Diminishing Marginal Substitutability corresponds to the older law of diminishing marginal utility. An indifference curve which lies above and to the right of another shows preferred combinations of the two commodities. The slope of an indifference curve shows the rate of substitution between two goods, i. This is known as the price ratio. Indifference curves are widely used in microeconomics to analyze consumer preferences, the effects of subsidies and taxes, and a few other concepts. When all such combinations are plotted on the graph and joined together with the help of a curve, we get an indifference curve as shown in Fig.
Taking the substitution effect and the income effect of the wage increase up to the wage rate W 2, the substitution effect is stronger than the income effect. Indifference curve is convex to the origin As mentioned previously, the concept of indifference curve is based on the properties of diminishing marginal rate of substitution. This is what is known as marginal decreasing replacement. When one arrives at two options that are indifferent to the individual, these two points that represent them are on the same indifference curve. This can be solved by constructing an Edgeworth-Bowley box diagram on the basis of their preference maps and the given supplies of goods.
Higher Indifference Curves Are Preferred to Lower Ones Consumers will always prefer a higher indifference curve to a lower one. Table: Indifference schedule Combination Mangoes Oranges A 1 14 B 2 9 C 3 6 D 4 4 E 5 2. The bottom part of the Fig. This means that combination L 10A+1B gives an equal level of satisfaction and utility as 9A+ 2B , 7A+4B and so on. When the wage rate increases, the new wage line becomes W 3L and the wage rate per hour-also increases and similarly for the wage line W 3 L. In particular, economists such as Edgeworth, Hicks, Allen and Slutsky opposed utility as a measurable entity.
Indifference curve map We can also show different indifference curves. . This ratio increases or decreases as the amount of good that already has the consumer. Suppose A would like to have more of X and S more of Y. However, both will be at an equal position of advantage at Q.
This is actually being done by the various state governments in India. Similarly, when his wage increases, to L 1, he works for longer hours L 2 L and with E 3 L 3 wage increase, he works for still longer hours L 3 L and enjoys lesser and lesser leisure than before. Indifference Curve Indifference Curve Definition: The Indifference Curve shows the different combinations of two goods that give equal satisfaction and utility to the consumers. Monotone implies locally insatiable, but not the other way around. The Diagram: To show how Indifference Curves are constructed let us take the example of a consumer purchasing two goods only, apple and orange. A set of indifference curves is known as an indifference map.
The Indifference Curve: Meaning, Property and Assumption
These properties are Indifference curve slope downwards to right An indifference curve can neither be horizontal line nor an upward sloping curve. Hence, it is critical to understand the preferences of the consumer as these vary from individual to individual and market to market. It is a graphical representation of an indifference schedule, which enlists all such combinations of the goods in a tabular form, giving exactly the same total satisfaction to the consumer. The Indifference Curve Example It is plotted simply by asking an individual what combination of goods he prefers, for example: 10 pens and 5 pencils; 15 pens and 3 pens; Or 20 pens and 2 pens. But in the next step, since only 3 pencils remain, if you want to remain indifferent, you must give 5 pens for a pencil. Thus an indifference curve may be defined as a curve which shows combinations of goods which are equivalent to one another.
Indifference Curve Analysis: Concept, Assumption and Properties
However, the theory assumes that a consumer can express utility in terms of rank. If the price of petrol rises, then it is relatively cheaper to go by bus. This assumption is called Transitivity. Once the consumer reaches this position he will not shift his purchase pattern, unless his income changes or unless the price of X or of Y becomes different. The following diagram will help you understand this property clearer. Say Media We partner with Say Media to deliver ad campaigns on our sites. If you preferences satisfy this property, you have convex preferences which can be represented by a quasi-concave utility function.
Later economists adopted the principles of indifference curves in the study of. Index Exchange This is an ad network. We take a situation when the subsidy is not paid in money but the consumers are supplied cereals at concessional rates, the price-difference being paid by the government. Instead of representing height, indifference curve represents a level of satisfaction. I put two slices of turkey on your plate, and a large scoop of mashed potatoes.
Indifference curve financial definition of indifference curve
An indifference schedule is a list of various combinations of commodities that give equal satisfaction or utility to consumers. Between these two extremes he will purchase both apple and orange, but will vary the proportions according to relative prices so that he obtains the advantages of small price changes of either commodity. On the other hand, the slope of the indifference curve measures the number of pens that the individual is willing to give up to get another pencil. If A has better bargaining skill than S, he can push the latter to point R. Let us consider the logical inferences or conclusions if the indifference curve does not slope downwards from left to right. Shows all combinations of goods that provide the consumer with the same satisfaction, or the same utility.
